  • Method for reducing microfoam in a spray-applied waterborne composition
    Patent number: 5334655
    Abstract: A method for reducing the amount of microfoam in a spray-applied clear waterborne polymeric composition is provided, wherein the clear composition contains certain emulsion-polymerized addition polymers or certain multi-staged emulsion-polymerized addition polymers is formed; is spray-applied to a substrate; and is dried. Also provided are substrates bearing such spray-applied clear compositions.
